Energetic salts based on 5-(5-Amino-1H-1,2,4-triazole-3-yl)-1H-tetrazole with good thermal stability

Abstract. Heat-resistant explosives play an irreplaceable role in special applications. Firstly, energetic salts with high thermal stability and energy performance, namely N2H5-ATT and NO3-ATT, were synthesized based on the amphoteric properties of 5-(5-Amino-1H-1,2,4-triazole-3-yl)-1H-tetrazole (H2ATT). And it was characterized through chemical (IR spectroscopy and single crystal XRD) and physicochemical analysis (friction, impact, electrostatic, and DSC testing). Research has found that it has high thermal stability, high heat of formation, and appropriate sensitivity. Their detonation performance (detonation velocity, detonation pressure, etc.) is calculated using the EXPLO5 program. Meanwhile, its detonation performance is comparable to high-energy potassium salts such as HNS, making it a promising heat-resistant explosive.
